  Cradle cap, or pityriasis capitis, is a subset of infantile seborrheic dermatitis (ISD). It is a very common, mostly self-limiting, chronic non-inflammatory scaling skin condition that presents between the third week and first couple months of life. The peak incidence is at 3 months of life. The skin manifestations are marked by erythematous plaques with greasy-appearing yellowish scale. Cradle cap’s name is analogous to its anatomical location. It can be found in areas dense in sebaceous gland activity, such as the scalp, T line of the face and external ears. […] Currently, there is no known cause for cradle cap. However, there are many factors that have been hypothesized to influence the condition. One hypothesis is the secondary influence of maternal circulating hormones resulting in overactive sebaceous gland activity. Sebaceous glands produce sebum, which is an oil-like substance. Overproduction of sebum causes the dead corneocytes (scale) to remain adherent instead of undergoing normal desquamation. Furthermore, the increase in frequency of seborrheic dermatitis during infancy and adolescence supports a hormonal influence on the condition. Malassezia, a yeast, has been implicated in many cases of cradle cap. The yeast breaks down sebum, consuming the saturated fatty acids, and subsequently leaves the unsaturated fatty acids behind. M. globosa and M. restricta have been found in over 80% of all age cases in an outpatient dermatology setting. The response from anti-fungals further strengthens this causal relationship. However, the yeast is also seen in a large quantity of normal patients, suggesting an independent susceptibility to the yeast.

  Cradle cap is the common term for seborrheic dermatitis of the scalp in infants. […] The exact cause of cradle cap isn’t known. It’s likely due to a combination of things. Too much skin oil (sebum) in the oil glands and hair follicles and a type of yeast found on the skin called Malassezia may play roles in the development of seborrheic dermatitis.

  https://en.wikipedia.org/wiki/Cradle_cap

  Cradle cap is not caused by bacterial infection, allergy or poor hygiene. […] Doctors do not agree on what causes cradle cap, but the two most common hypotheses are fungal infection and overactive sebaceous glands. Cradle cap is an inflammatory condition. […] Possibly it has to do with overactive sebaceous glands in the skin of newborn babies, due to the mother’s hormones still in the baby’s circulation. The glands release a greasy substance that makes old skin cells attach to the scalp instead of falling off as they dry. There is a relationship with skin yeasts (Malassezia furfur).

  Cradle cap causes crusty or oily scaly patches on a baby’s scalp. The condition isn’t painful or itchy. But it can cause thick white or yellow scales that aren’t easy to remove. […] The cause of cradle cap isn’t known. One factor may be hormones that pass from the mother to the baby before birth. These hormones can cause oil glands and hair follicles to make too much oil. This oil is called sebum. […] Another factor may be a fungus called malassezia (mal-uh-SEE-zhuh) that grows in the sebum along with bacteria. Antifungal treatments often help control symptoms. This supports the idea that malassezia is a cause. An example of an antifungal treatment is ketoconazole. […] Cradle cap isn’t contagious, and it’s not caused by poor hygiene.

  Cradle cap is probably caused by hormones from the mother. These hormones cross the placenta before birth. The hormones cause the oil glands in the skin to become overactive. They then release more oil than normal. […] Dead skin cells normally fall off. The extra oil causes these cells to „stick” to the skin. These cells form yellow crusts and scales on the scalp. […] It’s caused by overactive oil glands in the scalp.

  Seborrheic dermatitis is a chronic inflammatory disorder most commonly seen in infants and adolescents. […] The etiology of seborrheic dermatitis is unknown, although a few studies have indicated that the fungal organism Pityrosporum ovale (Malassezia furfur) plays a role. […] In these studies, the fungus was cultured in the majority of the seborrhea patients, but in very few control patients. […] In one study, treatment with ketoconazole resulted clinical cure in two-thirds of infants treated. […] However, these studies are controversial since M. furfur in other studies has been found to be part of the normal flora in healthy individuals.

  The exact origin of cradle cap is still unknown to this day. […] Even if we do not know the reasons for its appearance in young children, the mechanisms responsible for the appearance of cradle cap are well identified. […] Among the causes of cradle cap onset, excess sebum is the first. […] In the case of cradle cap, sebum is secreted in excess, so there is hyper-seborrhea on the surface of the skin. This excess of sebum is partly due to the mother’s hormones transmitted at the end of pregnancy. […] An environment rich in sebum promotes the proliferation of yeasts of the Malassezia genus. […] These yeasts, harmless in normal proportions, become pathogenic when they are present in large numbers.

  Cradle cap, “infantile seborrheic dermatitis”, is a collection of odd patches of a thick, yellowish, oily, greasy, scaly, dry, crusty skin condition that can soon develop on your baby’s scalp shortly after birth, for seemingly no reason at all. […] The American Academy of Pediatrics does not have a medical theory for cradle cap, nor do they have many causation factors. […] Your doctor may feel that there is a bacterial infection in the sebaceous glands caused by a fungus such as yeast triggering the infantile seborrheic dermatitis. […] Inflammation of the sebaceous glands can be caused by maternal hormones from the birthing process transferring to the baby in the womb, causing an increase production of sebum oil which eventually results in a blockage trapping flaky skin. […] Infantile seborrheic dermatitis is known to have an underlying bacterial imbalance in the gut causing yeast or fungal infections.

  Therefore, when underlying toxins increase due to gut dysbiosis, leaky gut and possibly SIBO (Small Intestinal Bacterial Overgrowth), they lay the groundwork for possible yeast and fungus infections in the body that the body will naturally try and eliminate or detox first through the skin. […] Yeast infections in cradle cap are typically from the Malassenzia (Pityrosporum) strain of yeast; both cradle cap and dandruff have been found to be caused by this specific strain of yeast. […] Antibiotics also contribute to cradle cap because they increase yeast infections which are known to trigger cradle cap.

• #1 Cradle Cap in Babies: Symptoms, Causes, and Natural Home Remedies

  https://www.tinyhealth.com/blog/cradle-cap-symptoms-causes-remedies

  Cradle cap, or infantile seborrheic dermatitis, is a common condition that affects about 10% of babies under a month old, then peaks around three months, affecting up to 70% of infants. […] The exact cause of cradle cap isn’t fully understood, but several factors may contribute. Your baby’s oil glands may produce too much oil (sebum), which can cause skin cells to stick to their scalp instead of shedding naturally. This extra oil may result from hormones passed from mom to baby, or other factors like dry air, temperature changes, or harsh skincare products that strip natural oils from the skin. […] Other causes may include issues with the skin’s protective barrier, changes in the amount or type of natural skin oils, an overactive immune response, and an imbalance in the skin’s natural bacteria and yeast.

  Cradle cap classically presents as greasy, non-inflammatory plaques with overlying yellowish scale, on the vertex and frontal regions of the scalp. Cradle cap is usually asymptomatic; neither painful nor pruritic. Most infants generally have no side effects from the condition with feeding and sleep not being interrupted. […] Cradle cap is generally a self-limiting skin condition. Prevention of cradle cap is difficult, secondary to the unknown cause of the condition, yet many believe hormones play a strong role. Moreover, the treatment for mild and localized cradle cap should remain conservative. The infant should be washed daily with a gentle baby shampoo along with an emollient (white petrolatum, mineral oil, baby oil) prior to the shampoo use. The emollient may prove more effective if remaining in contact with the skin for a prolonged period of time, overnight if necessary, to break up the scale. Afterward, there should be the gentle removal of scale with a soft toothbrush or cradle cap comb. The oil will help soften the scale making it easier for removal. Once the scale is removed, parents should continue daily shampooing of their infant’s affected areas to prevent recurrence. Cradle cap that does not improve after conservative measures or that is extensive in nature can be treated with an antifungal cream such as ketoconazole 2% or a topical steroid cream such as hydrocortisone 1% for approximately 1-2 weeks. […] Cradle cap is generally self-limiting and benign. Yet, if the condition persists after 12 months of age, alternative diagnoses should be further investigated.

  Cradle cap is a greasy, yellowish, scaly rash that appears in patches on the scalps of infants. It is not clear what causes cradle cap, but it may stem from overactive sebaceous glands, a fungal infection, or both. […] It is not clear what causes cradle cap, but it is not caused by allergy, bacterial infection, or bad hygiene. It may stem from overactive sebaceous glands, a fungal infection, or both. The sebaceous glands are found in the skin and produce an oil-like substance, known as sebum. Overactive sebaceous glands may produce too much sebum, and this could prevent the old skin cells from drying and falling off the scalp. Instead, they stick to the scalp. […] The reason why the glands are overactive may be because the mothers hormones stay in the babys body for a number of months after birth. If a fungal infection occurs, it could be the result of the mother taking antibiotics before giving birth, or because the baby was given them up to a week after birth. Antibiotics destroy bacteria that cause damage, but they can also destroy the useful bacteria that prevent things like fungal infection.

  Cradle cap is probably caused by hormones from the mother. These hormones cross the placenta before birth. The hormones cause the oil glands in the skin to become overactive. They then release more oil than normal. […] Dead skin cells normally fall off. The extra oil causes these cells to „stick” to the skin. These cells form yellow crusts and scales on the scalp. […] It’s caused by overactive oil glands in the scalp.

  Seborrheic dermatitis is a chronic inflammatory disorder most commonly seen in infants and adolescents. […] The etiology of seborrheic dermatitis is unknown, although a few studies have indicated that the fungal organism Pityrosporum ovale (Malassezia furfur) plays a role. […] In these studies, the fungus was cultured in the majority of the seborrhea patients, but in very few control patients. […] In one study, treatment with ketoconazole resulted clinical cure in two-thirds of infants treated. […] However, these studies are controversial since M. furfur in other studies has been found to be part of the normal flora in healthy individuals.

  The causes of seborrheic dermatitis are unknown, but it’s believed that one of the factors is an inflammatory response to Malassezia yeast on the skin. […] The following may contribute to the condition: Overgrowth of Malassezia yeast: This yeast is part of the group of organisms that normally live on the skin. It typically doesn’t cause any trouble, but can when there is too much of it. […] An inflammatory reaction that may happen in response to an excess of yeast, increased androgens, and/or increased skin lipids. […] The causes of seborrheic dermatitis are unclear, but researchers believe that it is likely due to several factors. […] Possible causes are an overgrowth of yeast and an inflammatory reaction to it or to increased skin lipids or hormone levels.

• #3 Cradle cap (infantile seborrhoeic dermatitis)

  https://dermnetnz.org/topics/cradle-cap

  Cradle cap, or pityriasis capitis, is infantile seborrhoeic dermatitis affecting the scalp. […] The cause of cradle cap is not known. It may be related to hyperactivity of sebaceous glands responsive to residual circulating maternal androgens. Malassezia has also been implicated although its exact role is not clear. […] Cradle cap is benign and self-limiting. It usually resolves without intervention over the course of weeks to several months. If disease persists beyond 12 months, the diagnosis should be reconsidered.
